MUSICAL BOX.

SPECIFICATXON forming part of Letters Patent No. 388,947, dated Sieptember t, 1888.

Application filed May 28. 18%.

To all whom it may concern.-

Be it known that l, JEAN BILLON-HALLER, manufacturer, residing at Geneva, in Switzerland, have invented a new and useful Improvement in Musical Boxes, of which the following is a specification.

My invention consists of an improved mechanism for musical boxes, especially for those boxes having interchangeable pin -cylinders and being acted upon by means of a handle. The purpose is, first, to secure the cover of the bearings of the cylinder-axes while the works are playing, and, secondly, to cause the axial displacement of the pin-cylinder by means of a very cheap and simple arrangement.

In the accompanying drawings, Figure 1 is a top view, and Fig. 2 an under side view, of a musical box constructed according to my invention and provided with an interchangeable pin-cylinder acted upon by a handle. Fig. 3 shows, on an enlarged scale, the lever B, and Fig. at the pins M. Fig. 5 is a side view of lever O, intended to effect the changing of the airs by means of cliclewheel q and regulator Q.

In all the figures similar letters refer to simi iar pieces.

Underneath the plate A there is placed a lever, B, which is pivoted to A by means of a screw, 1). This lever B is provided with a projection, B, which is continuously pressed against the rim f of the pincylinder F by a spring, 0, fixed to the plate A. The rimf of the pin-cylinder F is provided with a notch,

5 f, into which the projection B of B falls at the very moment the pinless part of the pincylinder arrives in front of the comb D-that is to say, at the end of each air. As shown in Fig. 3, the projection B is provided with a beveled part, upon which the rim f presses when the cylinder F revolves in the direction of the arrow, causing the lever B to return into its first position.

The motion of B is transmitted to a sliding bar, E, guided by two screws, 6, fixed to the plate A. This sliding bar E has two inclined parts, E E, which are placed underneath the pins M M, which pass through the bearings J and K of the cylinder F. The pins M are pressed against the said inclined. parts Serial No, 275.263. (No model.)

E of E by means of a spring, at, so as to be thrown out of the covers j and 7c of the bean ings J and K when the lever is placed in the position shown by Fig. 4, or to be pressed through said covers and 7.: when the lever E is moved from right to left in the direction of the arrow. The latter takes place when the lever B is in the position shown in full lines in Fig. 2 and the position of pin H shown in Fig. 4 corresponds to the position of lever B shown by dotted lines in Fig. 2. The purpose of this arrangement is to have the pins M traversing and lining the covers j and L of the bearings J and K so long as the air is playing, and to have them movable when the cylinder is in its starting position for the purpose of replacing the cylinder by another one in turning the covers 3 and 7c in the direction of the arrows shown in Fig. 1. The lever B and spring 0 are further intended to exert a lateral pressure against the cylinder F in the direction of its axis, so as to insure the cylinder being contini'iously pressed against the sliding piece U, which bears against the disk Q, provided with as many catches as there are airs upon the cylinder.

The disk Q, is the well-known regulating mechanism of the axial position of the pin cylinder used in musical boxes; but, in place of having the same a'iiixed to the cylinder itself, I alfix it to the fixed bearing It, so as to use only one disk Q for several interchange able cylinders F. The disk Q is connected to a click-wheel, q, and may be turned with a view to change the airs by means of cliclelever 0, bearing a click, 1?, with spring 1*.

Having thus described my invention, I claim- 1. In a music-box, the combination, with the cylinder F, having a rim, f, and notch f, of the horizontallynnoving pivoted lever B, having a lateral projection, B, a spring, G, acting against the edge of the lever B, and with mechanism, substantially as specified, for allowing the spring 0 to move the projection and engage it with the notch f at the end of each tune or air, substantially as set forth.

2. The combination of lever B with the lever E and the pins M, substantially as shown and described, and for the purpose specified.

8. The combination of spring 0, lever B, to this specification in the presence of two suband cylinder F with the bearing R, to which scribing witnesses. is affixed a disk, Q, with sliding piece U, clickwheel 4 lever 0, click P, and spring v, sub- 5 stantially as shown and described, and for the Witnesses:

purpose specified. E. IMER-SCHNEIDER,

In testimony whereofI have signed my name TH. TRUCA.
